At Cups and Mugs in Fairfax, county health inspectors closed the coffee shop citing "critical health code violations." Inspectors wrote-up the shop for not staffing anyone certified in food safety, not tracking workers' disease status, and not having required soap and paper towels.

In Washington's Woodley Park community, inspectors closed the white table clothed restaurant Rajaji located on Connecticut Avenue. They were cited for 12 health code violations. Included on the list: mold on the ice machine, no thermometer in the walk-in refrigerator, employees making ready to eat food with bare hands and a problem with rats.

When WUSA9 investigative reporter, Russ Ptacek, was invited into the kitchen at Rajaji's, he found evidence of rodent droppings. Management cleaned up the mess and said it's launching an intensive extermination attack on the rats. Rajaji management said it's doing everything it can to meet health code requirements and invited us to come back, unannounced, anytime. They promised us a better, cleaner kitchen.

On South Capitol Street in Southwest DC, at ZMart, inspectors closed the market for rat droppings and for not having anyone on staff certified in food safety.When WUSA9 looked around, we also found rodent droppings and the certified food manager was not on site.

And in Prince George's County, health inspectors closed Mauricio's on Bladensburg Road for operating without a food service permit.

Since WUSA9 visited these establishments, most of them passed re-inspection and are back in business. However when WUSA9 called Mauricio's and Taipei 101 Tokyo Cafe--there was no answer. Phones at both restaurants were out of service.
